(i)其中y表示液体在t时间内移动的距离，n和K是常数取决于温度和特定物质。理论的讨论。泊泽伊研究了液体通过毛细管从一个水平面到另一个水平面的运动。8在他的实验中，毛细管的两端开成一个大的储层，液体通过的毛细管的长度是恒定的。结果表明，在给定时间内，通过管道的水量与两个储液器中液体的液位差成正比，与管道直径的四次方成正比，与管道长度成反比，前提是管道长度与直径相比非常长。这可以用方程来表示，其中Q是单位时间内通过的液体量，H是水位差，D和L分别是毛细管的直径和长度，C是常数。这个公式可以应用于前进
Kt,(i) where y represents the distance through which the liquid has moved in the time t, and n and K are constants depending on the temperature and the specific substances. Theoretical Discussion.—The movement of a liquid from one level to another through a capillary tube has been studied by Poiseuille. 8 In his experiments the ends of thecapillary tube opened into large reservoirs, and the length of the capil-lary tube through which the liquid passed was constant. The results show that the amount of water which passes through the tube in a given time is proportional to the difference in level between the liquid in the two reservoirs, proportional to the fourth power of the diameter of the tube, and inversely proportional to the length of the tube, provided the length is very long in comparison with the diameter. This is expressed by the equation where Q is the amount of liquid which passes through in unit time, H is the difference in level or “head,” D and L are the diameter and length of the capillary tube respectively, and C is a constant. Thisformula may be applied to the advance
